EXCEL {=SUMPRODUCT(1/COUNTIF(A1:A7,A1:A7))}
EXCEL {=SUMPRODUCT(1/COUNTIF(A1:A7,A1:A7))}
=SUMPRODUCT(1/COUNTIF(A1:A20,A1:A20)) 与=sum(1/COUNTIF(A1:A20
excel中求区域A1:A100内不重复的数据个数的公式:=SUMPRODUCT(1/COUNTIF(A1:A100,A
excel表格要求是 A1=B1,A7=B2,A14=B3,怎么样做的?
excel如何求差a1:a3=a4:a6-a7:a9?
若COUNT (A1:A7)=2,则COUNT (A1:A7,3)=?
您好,第二个:=SUMPRODUCT((1/COUNTIF(B1:B11,B1:B11))*(A1:A11=2800))
=sumproduct(1/countif(A1:A20:A1:A20)) 请帮我用文字描述下这个公式的计算过程,
已知一列数a1,a2,a3,a4,a5,a6,a7,且a1=1,a7=729,a1/a2=a2/a3=a3/a4=a4/
=SUMPRODUCT(--LEFT(A1:B1,FIND("+",A1:B1)-1))&"+"&SUMPRODUCT(
用sumproduct(1/countif(a1:a5,a1:a5))时,如何忽略其中的空值:
excel中,公式“=COUNTIF(A1:A10,A1)“与“=COUNTIF(A1:A10,A1:A10)”的结果是
